Using equations he develops, he is able to predict the exact arrangement of electrons in many atoms, and from there predict why they are where they are in the Periodic Table.

1. Marie Curie was a Polish scientist that specialized in chemistry and physics. She wanted to understand how X-rays worked and noticed in her studies that the element, Uranium, gave off rays that could be measured but did not know what the rays were. She assumed that the rays came from the uranium itself instead of through different molecules interacting with each other. To study the rays, she used an instrument, called an electrometer, that studied the electricity that the rays passed through the air. Through this she was able to discover that the more uranium atoms there were in a compound, the stronger the rays that came off of it. She used this discovery to test other minerals that emitted more rays than Uranium, and discovered the elements Thorium, Polonium and Radium. Through her discoveries of these elements, scientists were able to find the structure of the atom and even how the rays can be used to fight cancer. What was Marie Curie’s observation? 2.

In the table below, there are descriptions of an experiment on samples of three different chemical elements. Decide whether the element is a metal or nonmetal, if you can. If there is not enough information to decide, choose can't decide in the third column. element description metal or nonmetal? Element 1 is a hard silvery-gray solid. Wires are fastened to each side of a 2 cm slab of it, and an ordinary household 9 V battery is hooked up so that it can feed electricity through the slab to an LED. The LED glows brightly. metal 1 nonmetal (can't decide) Element 2 is a moderately soft silvery-gray solid. A 5 cm × 5 cm square of it, only 1 mm thick, is pressed into a dish-shaped mold under high pressure. When the press is lifted up, the sample has been crushed to a powder. metal 2 nonmetal (can't decide) metal Element 3 is a moderately soft silvery-gray solid. A 5 cm x 5 cm square of it, only 1 mm thick, is twisted using two pairs of pliers, giving it a slight curve. 3 nonmetal (can't…

Order the theories from oldest to most recent. START ORDER Atoms consist of mostly empty space with a dense nucleus of positive charge. Atoms are tiny indivisible particles that make up all matter. Electrons occupy specific energy levels surrounding a positively charged nucleus. Electrons move about a positively charged nucleus in clouds that are defined by probabilities. Negatively charged electrons are embedded in a mass of positive charge. END ORDER
